MACHINE FOR SOLDERING END PIECES ON CANS.

SPECIFICATION forming part of Letters Patent No. 405,822, dated June 25,1889. Application filed December 10, 1888. Serial No. 293,088- (Nomodel.)

To all whom it may concern.

Be it known that I, JAMES A. BOOTH, of Boston, county of Suffolk, Stateof Massachusetts, have invented an Improvement in Machines for SolderingEnd Pieces 011 Cans, of which the following description, in connectionwith the accompanying drawings, is a specification, like letters on thedrawings representing like parts.

This invention has for its object to 0011- struct a machine forsoldering heads or end pieces on can-bodies.

In accordance with this invention, the cylinder or can-body, havingplaced on its lower end a flanged head or end piece, is conveyed by asuitable holder into position between two spindles, preferably a liveand a dead spindle. Mechanism is provided for moving one of the spindlestoward the other to clamp between them the can-body and its holder.Suitable mechanism is provided for rotating the live-spindle to impartrotary motion to the can-body. A suitably-shaped trough or receptacle isemployed, it being so arranged as to deliver hot solder at a singlepoint to the flange of the head or end piece, or between the flange andthe can-body, so that as the ean-body is rotated the hotsolder will beproperly delivered entirely around the flange. A heater of any suitableconstruction is employed to keep the solder trough or receptacle hot.The holders will be made of any suitable size to accommodate cans ofdifferent sizes.

Figurel shows in side elevation a machine for soldering heads or endpieces on can-bodies embodying this invention; Fig. 2, a plan view ofthe machine shown in Fig. 1; Fig. 3, a detail of the hot-solder troughor plate; Fig. et, a sectional detail of one of the holders; Figs. 5 and6, details of the live-spindle, to be referred to; Fig. 7, alongitudinal section of the machine shown in Fig. 2, taken on the dottedline so The. main frame-work comprises, essentially, the table a andlegs I). A metallic bed-plate a is secured or set into the top of thetable a, it having two upwardly-extended parallel projections a at ornear its center, presenting a guideway for a rectangular block a fittedto slide therein. (See Figs. 2

and '7.) A rod a is fixed to the block (Krising vertically thereon, uponwhich rod is mounted a collar 1), having a set-screw a by which it maybe secured in any desired position thereon. A hub a is placed loosely onthe rod o resting on the collar p.

Several arms, herein shown as four in number, as a (t a a", radiate fromthe hub a in a plane parallel wit-h the bed-plate, and at the terminusof each arm a block is fixed, which is bored centrally to receive theShank eof a holder. Each holder comprises a disk 0', recessed upon itsunder side to receive a canbody h, and attached centrally to the shankc. The shanks c of the holders are made long enough to extend up throughthe blocks, and pins 2 are placed in holes in the shanks to preventremoval of the holders from the blocks. The holders are therebypermitteda limited vertical movement. AS the hub a is loose 011 the roda the arms carrying the holders may consequently swing freely, and theholders being loosely held by the blocks or holes formed in the ends ofthe arms, may also be revolved independently.

A chain or cord (1 is attached to one end of the block a it passing overa roller d and being connected to the treadle-rod (Z of a treadle cl. Aspring (1 (see Fig. 7 and dotted lines, Fig. 2) is attached one end tothe opposite end of the block a and the other end to a post (1. By meansof the treadle d the block a may be moved in the direction of the arrow,Fig. 2, while the tendency of the spring is to return the block.

A dead-spindle e is fixed to one end of an arm or cross-bar e, and atthe opposite end of the said cross-bar a guide-rod e is fixed, saidspindle and guide-rod passing through holes formed in a cross-bar 6adapted to be held stationary and serving as a guide. A spring ea-surrounds the spindle 6 between the bars 6 6 the tendency of which isto normally keep the cross-bar e in elevated position. A treadle rod 6connects the bar 6' with a treadle 6, so that by depressing the saidtreadle the crossbar e and its dead-spindle c will be depressed. The bar6 is attached to an upright or bracket f by screws f passing through theplate a to which the bar 6 is rigidly attached at substantially rightangles thereto, and thence through slots in the said bracket, so thatvertical adjustment of the IOC bar e? is obtainable, The live-spindle 11is mounted in the bed-plate, and has at its iipper enda smalldisk-'6,which revolves in'a plane parallel with the bed-plate, but slightlyabove it.

The spindle 2' (see dotted lines, Fig. 6) revolves in a bearing 71 whichis held statio'iig ary by lugs 71 secured to the under side of the tableby suitable bolts it g has at its lower end a bevel-toothed gear '5which is engaged by a bevel-toothed gear "6 fixed to a horizontal shafti having its bearings in brackets on the under side of the table. 'Abelt-pulley or hand-wheel is fixedto said shaft 2' for rotating it, andthereby rotating the live-spindle. v p I solder trough, plate, or shelf72 is secured tds "table brackets n attached to the main renewed, saidplate a utting against the edge of the be'dEpIat-e a, and having a semicircular recessin 's'aid abutting edge to 1 re cei'v'e in partconcentrically the disk if of the live s'pindle. The plate a is mademuch thicker than the bed-plate, or so as to lie abovea plan ith saidbed-plate, and the semicirciirecess nf has an annular groove a, ("seeFig; 3,) the lower edge 'ofwhich lies snbstan tiauy flush with the topof the disk t. The plate *rt has small recess n? in its top, serv ing asdelivery for the solder from the top of the plate to a point near theannular groove nib Thesolder plate n is heated by any suitable heatingapparatus, an ordinary Bunsen ut i n attached to a gas-pipe, n beingherein shqwn The burner n is placed in a chamber, three sideslof which,are for ine'dby the brackets b the chamber being provided witha flue n,ahd directly beneath the plate n,tli'e bottom of said chamber being theplate m to which the brackets n are attached by suitable bolts n (seeFig. 1,) which passthrough slots n? in the plate a (see Fig.2) to admitof adjustment of the same toward the b'efd plat'e a; 7

In operating the machine a can-body h,- hav ingfa flanged head or endpiece K precedes itslower end, is placed on the plate ttflbe- Heath oneof the holders c, the hold lifted to receive it, and the o in g thecan-body, ii'fve's the "Sam I ldisktf', dea'a sp nplate and lifts i'tnp" lif 'ag ainstf he 5 1mg held b'et livespindle 1 flanged tea, or t eresting spindle bears y npontlie up};
